Analysis Of Surgical Approach And Prognosis Of Anterior Communicating Artery Aneurysm

Objective:To evaluate the positional relationship between the A2 segment of the anterior cerebral artery and the direction of the anterior communicating artery aneurysm,to analyze the side of the surgical approach,to reduce the complications and improve the prognosis of the patients.Methods:This paper retrospectively analyzed 72 patients with anterior communicating artery aneurysm from November 2014 to October 2016 by microsurgical treatment of pterional approach.According to the preoperative cranial CTA,the simulated two-sided pterional approach revealed the anterior communicating artery aneurysm.All cases were divided into left and right aneurysms,while the anterior communicating artery aneurysm according to the direction and plane relationship is divided into I~V: Type I,aneurysm pointing forward;Type II,aneurysm pointing upward;Type III,aneurysm pointing down;Type IV,aneurysm after the point;Type V,aneurysm lobulated.Complete the same side,the opposite side of the pterional approach,Compared two groups of surgical approach by A2 segment covered tumors,Hunt-Hess classification,aneurysm tumors had directed,postoperative postoperative 1d GCS(Glasgow coma Scale),within 3 months after Glasgow Outcome score(Glasgow Outcome Scale,GOS),etc.Results:Ipsilateral and contralateral surgical approach in the two groups Hunt-Hess classification statistically significant(P<0.05).There was no significant difference between the two groups of the relationship between the A2 segment on the anterior or posterior and the aneurysm covered by A2 segment of the anterior cerebral artery(P>0.05).On the postoperative postoperative 1d GCS(Glasgow coma Scale),within 3months after Glasgow Outcome score(Glasgow Outcome Scale,GOS),The difference between the two groups was statistically significant(P<0.05).Compared two groups on the prognosis of five type of aneurysm,results showed that there was no significant difference(P>0.05).Conclusion:clip aneurysm by Ipsilateral pterional approach is more safe and reliable,Two side of pterional approach of Ipsilateral and contralateral surgical approach can be choosed by personal habits,andformulate individualized programs.
